Description

    TECHNICAL FIELD
  • This disclosure relates to wellbore operations, for example, wellbore drilling and makeover operations.
    • BACKGROUND
  • Hydrocarbons trapped in subsurface reservoirs can be raised to the surface of the Earth (that is, produced) through wellbores formed from the surface to the subsurface reservoirs. Wellbore drilling systems are used to drill wellbores through a subterranean zone (for example, a formation, a portion of a formation or multiple formations) to the subsurface reservoir. Wellbore drilling operations involve lowering well tools into the wellbore and perform operations inside the wellbore using the lowered tools. Cementing is one such operation in which cement is flowed from the surface to a downhole location and allowed to harden. The cement is flowed through a cement retainer. In some instances, removing the cement retainer or other cement-flowing tool from the wellbore can be more expensive than simply milling through the tool and flowing the resulting debris from within the wellbore.

    • DETAILED DESCRIPTION
  • Wellbore operations including cementing operations performed during drilling and workover. In one run (or trip) a cement retainer is lowered into a wellbore and is installed (or set) at a desired downhole location. Cementing operations are then performed by flowing cement through the cement retainer. In another, separate run (or separate trip), a wellbore milling tool is lowered into the wellbore to mill the cement retainer and the top of the cement to a desired depth. This disclosure describes a well tool and a method associated with the well tool that will enable a one-trip system to set the cement retainer, perform the cementing operation and mill through the cement retainer. By “one-trip,” it is meant that the well tool that can perform the cementing operation and the milling operation is lowered into the wellbore in a single trip. Further, without needing another trip and using components of the well tool already lowered into the wellbore during the single trip, the cementing operation and then the milling operation are performed at the downhole location within the wellbore. By reducing multiple trips to a single trip, time to implement the excess, time to set up a rig to implement the excess trip and costs and equipment associated with excess trips can be reduced. Human error that results in choosing a milling tool of incorrect size or type can be reduced or eliminated by implementing the operations described in this disclosure.
  • FIG. 1 is a schematic diagram of an example of a well 100 with the well tool 102 described in this disclosure. The well 100 includes a wellbore 104 formed from a surface 106 through a subterranean zone 108 towards a subsurface reservoir (not shown). The well tool 102 is lowered into the wellbore 104 to a desired downhole location 110. At the downhole location 110, the well tool 102 is installed or set. Setting the well tool 102 at the downhole location 110 isolates a well region 112 downhole of the downhole location 110 from a well region 114 uphole of the downhole location 110. As described below and with references to the following figures, the well tool 102 can be used to perform cementing operations in which cement is flowed from the surface 106, through the well tool 102 and to the well region 112 downhole of the downhole location 110. Then, without raising the well tool 102 out of the wellbore 104 and without lowering another well tool into the wellbore 104 (i.e., in a single trip), portions of the well tool 102 are milled. The resulting debris can be flowed out of the wellbore 104 during a subsequent well operation.
  • FIGS. 2A and 2B are schematic diagrams of a tool layout of the well tool 102 of FIG. 1 . FIGS. 2A and 2B show the well tool 102 disassembled and assembled, respectively. The well tool 102 includes a string 202 that can be lowered into the wellbore 104 from a rig or equipment disposed at the surface 106 of the wellbore 104. For example, the string 202 can include coiled tubing, wireline, slickline or similar wellbore tubulars. A wellbore milling tool 204 is attached to an end of the string 202 that is lowered into the wellbore 104. The wellbore milling tool 204 can perform wellbore milling operations. That is, the tool 204 can mill through components installed in the well. To do so, the string 202 can be rotated to cause the wellbore milling tool 204 to rotate. Or, the string 202 can be periodically raised and lowered to cause the wellbore milling tool 204 to also be raised and lowered. During such rotational or axial motion, the wellbore milling tool 204 mills through any component that contacts the tool 204.
  • In some implementations, a fluid flow pathway (FIGS. 3A-3D) is formed through the wellbore milling tool 204. For example, the fluid flow pathway is formed as a hollow portion extending from one end of the tool 204 to the other end of the tool 204. The string 202 is also hollow and axially coupled to the fluid flow pathway formed in the tool 204. Fluids, e.g., cement, can be flowed through the fluid flow pathway from the surface 106, through the string 202 and through the fluid flow pathway formed in the tool 204.
  • The well tool 102 includes an elongate body 206 that is hollow and defines different portions (i.e., axial length segments) of different sizes. That is, while all the axial length segments are hollow, an inner diameter and an outer diameter of one axial length segment is different from an inner diameter and an outer diameter, respectively, of another axial length segment. The body 206 includes a first portion 208 near a first end of the body 206 and a second portion 210 near a second end of the body 206. The first portion 208 has an inner diameter that is greater than an outer diameter of the milling tool 204. The first portion 208 has an axial length equal to or greater than an axial length of the milling tool 204. In this arrangement, the milling tool 204 can be positioned and completely contained within the first portion 208, as shown in FIG. 2B. The remainder of the body 206 forms a second portion 210 that can have the same or different outer diameters. But, the outer diameter of the milling tool 204 is greater than the largest outer diameter of the second portion 210. In this arrangement, the milling tool 204 can mill through an entirety of the second portion 210.
  • A packer 212 (or similar sealing assembly) is attached to the second portion 210, e.g., nearer to an end of the second portion 210. The packer 210 allows the well tool 102 to be installed or set within the wellbore 104 at the desired downhole location 110 as described with reference to FIG. 1 . In some implementations, an outer diameter of the axial length of the second portion 210 to which packer 212 is attached is equal to an outer diameter of the milling tool 204 so that the milling tool 204 can mill through the packer 212 without damaging the packer 212.
  • The hollow portions that extend from end to end within the body 206 extend the fluid flow pathway defined by the milling tool 204. Fluids, e.g., cement, can be flowed through the fluid flow pathway from the surface 106, through the string 202, through the fluid flow pathway formed in the tool 204, through the hollow portions within the body 206 and to locations downhole of the tool 102. In particular, the cement can be flowed through the well tool 102 to the well region 112 (FIG. 1 ) downhole of the downhole location 110 (FIG. 1 ).
  • A tool retainer (FIGS. 3A-3D) is attached to the body 206. The tool retainer is configured to retain the milling tool 204 within the first portion 208 and to allow lowering the milling tool 204 attached to the body 206 within the wellbore 104. As described below with reference to FIGS. 3A-3D, once the well tool 102 has been installed or set within the wellbore 104 at the desired downhole location 110, the tool retainer can be activated to allow the milling tool 204 to separate from the body 206. In operation, the tool retainer is activated after the cementing operations have been performed by flowing cement through the fluid flow pathway.
  • FIGS. 3A-3D are schematic diagrams of an example of an operation of the well tool 102. FIGS. 3A-3D show the milling tool 204 (FIG. 2 ), attached to the string 202 (FIG. 2 ), wholly contained within the first portion 208 and lowered into the wellbore (not shown in FIGS. 3A-3D). As described above, the tool 102 defines a fluid flow pathway 302. Also, as described above, the tool retainer retains the milling tool 204 within the first portion 208 such that the milling tool 204 and the body 206 (FIG. 2 ) can be lowered into the wellbore 104 (FIG. 1 ) together in a single trip. In some implementations, the tool retainer includes a shear pin 304 that passes through a circumferential surface 306 of the body 206 (specifically, the first portion 208). The tool retainer also includes a notch 308 formed on a side of the milling tool 204. When the shear pin 304 is radially inserted through the circumferential surface 306 into the notch 308, the shear pin 304 locks the milling tool 204 and the first portion 208 such that the two components move together axially within the wellbore 104 (FIG. 1 ). After the well tool 102 is set at the desired downhole location 110 (FIG. 1 ) by deploying the packer 212 (FIG. 2 ), a relative axial movement between the milling tool 204 and the body 206 causes the shearing pin 304 to be sheared. For example, the shearing pin 304 can be made of a material that can be sheared when the string 202, to which the milling tool 204 is attached, is pulled in an uphole direction after the packer 212 (FIG. 2 ) has been deployed.
  • FIG. 3A shows that the first portion 208 with the milling tool 204 retained by the tool retainer is lowered into the wellbore 104 (not shown in FIG. 3A). The packer 212 (not shown in FIG. 3A) is deployed once the body 206 reaches the desired downhole location 110 (not shown in FIG. 3A). The fluid flow pathway 302 extends from the surface 106 of the wellbore 104 through the string 202 and the milling tool 204, through the hollow portion defined by the body 206 to the downhole end of the body 206. In some implementations, a separate elongate hollow tubular 302 can be disposed within the body 206 and connected (e.g., axially, end-to-end) to the milling tool 204. The tubular 302 can extend from the downhole end of the milling tool 204 to the downhole end of the body 206. FIG. 3B shows fluids, e.g., cement, being flowed through the fluid flow pathway 302. The cement is flowed from the surface 106 of the wellbore 104 to the wellbore region 112 (FIG. 1 ) that is downhole of the desired downhole location 110 (FIG. 1 ) where the packer 212 is deployed. FIG. 3C shows that the cement flow through the fluid flow pathway 302 has been stopped. The string 202 is pulled axially in an uphole direction causing the shearing pin 304 to be sheared. Consequently, the milling tool 204 is no longer connected to the first portion 208 of the body 206.
  • FIG. 3D shows the milling tool 204 being raised uphole of the body 206 (specifically, uphole of the first portion 208). The string 202 can then be rotated or moved axially in an uphole-downhole direction (or both), and the milling tool 204 can be brought into contact with the body 206 to mill the body 206. Because the inner diameter of the first portion 208 is greater than the outer diameter of the milling tool 204, the axial uphole-downhole motion can be implemented to contact the milling tool 204 against the first portion 208 to mill the first portion 208. Because the outer diameter of the milling tool 204 is greater than an outer diameter of the remainder of the body 206, the rotational motion of the milling tool 204 can mill the remainder of the body 206. The shearing pin 306 and any other component of the tool retainer are made of millable materials that can also be milled by the milling tool 204. In this manner, the cementing and milling operations are implemented in one-trip. That is, a separate trip to lower a milling tool to remove the body is unnecessary. In addition, the milling tool 204 need not be removed from within the wellbore 104 to mill the body.
  • FIG. 4 is a flowchart of an example of a process 400 of using the well tool of FIG. 1 . At 402, the well tool 102 is formed by positioning the milling tool 204 within the first portion 208 of the body 206. At 404, the milling tool 204 is connected to the body 206, specifically the first portion 208, by the tool retainer. At 406, the well tool body 206 with the connected wellbore milling tool 204 is lowered into the wellbore 104. At 408, the body 206 is installed within the wellbore 104 at the desired downhole location 110, for example, by deploying the packer 212. After the installing, the body 206 is sealingly attached to an inner wall of the wellbore 104 at the downhole location 110. At 410, after installing the body 206, cement is flowed through the fluid flow pathway (the cement flow pathway) to the wellbore location 112 that is downhole of the downhole location 110. At 412, after flowing the cement (specifically, after ceasing the flow of cement), the tool retainer is activated to separate the milling tool 204 from the body 206. At 414, after separating the milling tool 204 from the body 206, the body 206 is milled with the milling tool 204. In this manner, flowing of the cement and milling of the body 206 are implemented in a single trip into the wellbore 104.
  • Thus, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking and parallel processing may be advantageous.
